Definitions

  • the present invention relates to a thread gripping device in circular knitting machines for hosiery or the like.
  • the portion of thread that lies between the corresponding thread guide and the end formed by the cut is kept in a position that allows to resume knitting with that thread.
  • thread guides are arranged around the needle cylinder just above its upper end, and in order to prevent the needles from engaging the thread the thread dispensing end of said thread guides is raised.
  • a circular cutter which is arranged coaxially to the needle cylinder and has a slightly smaller diameter than the cylindrical surface traced by the needles as a consequence of the rotary motion of the needle cylinder about its own axis. Said cutter is provided with a plurality of teeth and generally rotates at the same speed as the needle cylinder.
  • the retention performed by the aspirator port may be insufficient, and the thread, after cutting, might contract and return toward the dispensing end of the thread guide due to elastic reaction, to the point of sliding out of said thread guide, making it impossible to subsequently resume knitting with that thread.
  • thread gripping devices downstream of the thread guides of a feed along the direction of rotation of the needle cylinder with respect to the thread guides there are thread gripping devices, which are designed to perform a firmer and more reliable retention of the thread when it is cut.
  • One of the thread gripping devices currently used in circular knitting machines or hosiery knitting machines comprises a supporting element, which is fixed to the structure of the machine that supports the thread guides proximate to a feed or drop.
  • Said supporting element supports at least one elastic lamina element and a thread locking lever, which is pivoted to the supporting element and can rotate in a scissor-like fashion with respect to the elastic lamina element in order to catch the thread directly before it is cut and clamp it between the locking lever and the elastic lamina element.
  • the locking lever and the elastic lamina element are arranged on planes that are substantially radial with respect to the needle cylinder and are located above the needle cylinder.
  • the locking lever has, on its lower side, which faces the upper end of the needle cylinder, a lug that forms a shoulder that is directed toward the axis of the needle cylinder.
  • the locking lever In order to grip the thread, the locking lever is turned about its own pivoting axis, on its plane of arrangement, which lies substantially radially with respect to the needle cylinder, so that its lower end moves transversely to the path of the thread in order to engage said thread by means of said shoulder and move the thread toward the axis of the needle cylinder and grip it between said locking lever and the elastic lamina element.
  • the thread moves accidentally toward the axis of the needle cylinder, with the gripping device described above the shoulder of the locking lever, in its movement toward the axis of the needle cylinder, cannot engage the thread, and therefore the device is unable to grip the thread.
  • the aim of the present invention is to solve the problem noted above, by providing a device for gripping thread in circular hosiery knitting machines or the like that provides great assurance of thread grip during thread cutting.
  • an object of the invention is to provide a device that ensures correct thread grip even if, at the end of the thread feeding step or during its engagement for gripping, the thread moves abnormally toward the axis of the needle cylinder.
  • Another object of the invention is to provide a structurally simple device that can be installed on a wide range of circular hosiery knitting machines or the like.
  • a device for gripping thread in circular hosiery knitting machines or the like comprising a supporting element that can be fixed to the structure of the machine that supports the thread guides proximate to a drop or feed, above the needle cylinder and proximate to the needle work area, said supporting element bearing at least one elastic lamina element that is arranged on a plane that lies substantially radially with respect to the needle cylinder, said supporting element furthermore supporting a thread locking lever that is pivoted to said supporting element with one of its portions and has a pivoting axis that is orientated substantially at right angles to the plane of arrangement of said elastic lamina element, said locking lever being laterally adjacent to said elastic lamina element and having a grip portion that can engage the thread dispensed by at least one thread guide at the corresponding feed or drop, actuation means being provided for actuating said locking lever for its scissor-like rotation with respect to said elastic lamina element about said pivoting axis
  • the device according to the invention comprises a supporting element 2, which can be fixed to the structure of the machine that supports the thread guides 3, proximate to a drop or feed, above the needle cylinder 4 and proximate to the needle work area 5.
  • the supporting element 2 supports at least one elastic lamina element 6a and 6b, which is arranged on a plane that is substantially radial with respect to the needle cylinder 4.
  • the supporting element 2 further supports a thread locking lever 7, which is pivoted to the supporting element 2, with one of its portions, about a pivoting axis 7a, which is substantially perpendicular to the plane of arrangement of the elastic lamina element 6a and 6b.
  • the locking lever 7 is laterally adjacent to the elastic lamina element 6a and 6b and has a grip portion 8, which can engage the thread 9 dispensed at the corresponding feed or drop of the machine.
  • the device comprises means 10 for actuating the locking lever 7 in order to produce its scissor-like rotation, with respect to the elastic lamina element 6a and 6b, about the pivoting axis 7a for the passage of the locking lever 7 from an inactive position, shown in Figure 2, in which the grip portion 8 of the locking lever 7 is moved away from the elastic lamina element 6a and 6b in the opposite direction with respect to the axis of the needle cylinder 4, to an active position, in which said grip portion 8 is closer to, and laterally superimposed on, the elastic lamina element 6a and 6b, in order to grip the thread 9 between the elastic lamina element 6a and 6b and the locking lever 7 and vice versa.
  • the grip portion 8 has two mutually opposite shoulders 11a and 11b, which delimit bilaterally the movement of the thread 9 toward or away from the axis of the needle cylinder 4.
  • the elastic lamina element 6a instead of a single elastic lamina element, which might be constituted by the elastic lamina element 6a, there are two elastic lamina elements 6a and 6b, which are arranged side by side and can flex elastically toward or away from each other.
  • At least the portion of the locking lever 7 that is meant to wedge itself between the pair of elastic lamina elements 6a and 6b is flat, and at least the region 7b thereof meant to be the first to penetrate between the elastic lamina elements 6a and 6b in passing from the inactive position to the active position is wedge-shaped.
  • the side of the pair of elastic lamina elements 6a and 6b that is directed toward the locking lever 7 in the inactive position is bent so as to form a guiding flared portion 6c for the wedging of the locking lever 7 between the pair of elastic lamina elements 6a and 6b.
  • the device is meant to be mounted above the needle cylinder 4, so that the lower side of the locking lever 7, on which the shoulders 11a and 11b are formed, lies above the circular cutter 12 usually provided in circular knitting machines or hosiery knitting machines, and the elastic lamina elements 6a and 6b lie within the cylindrical surface traced by the needles 5 as a consequence of the rotation of the needle cylinder about its own axis.
  • the locking lever 7, in the inactive position shown in Figure 2, is arranged so that the region located between the shoulders 11a and 11b lies at the path of the thread 9 at the end of its feeding to the needles 5 of the machine, as will become better apparent hereinafter.
  • the shoulders 11a and 11b have an undercut region, which forms a receptacle for retaining the thread 9 so as to assuredly prevent the thread from exiting from the region of the locking lever 7 that is indeed delimited by the shoulders 11a and 11b.
  • the axis 7a for pivoting the locking lever 7 to the supporting element 2 is arranged above the region of mutual lateral overlap of the locking lever 7 with the elastic lamina elements 6a and 6b.
  • the actuation means 10 comprise a pneumatic cylinder 20, which is connected to, or integrated with, the supporting element 2.
  • the pneumatic cylinder 20 is formed directly within the supporting element 2. More particularly, in the supporting element 2 there is a cylindrical chamber 21, which slidingly accommodates a piston 22, which acts on a region of the locking lever 7 that lies between the pivoting axis 7a and the elastic lamina elements 6a and 6b.
  • the chamber 21 has an opening that is connected to a supply connector 23, which can be connected selectively to a compressed air line or to a vent in order to produce the translational motion of the piston 22 toward the locking lever 7 or to allow the sliding of the piston 22 in the opposite direction, in a per se known manner.
  • the region 40 of the locking lever 7 that is in contact with the thread 9 during its gripping is made of a material that has a higher friction coefficient, in relation to the thread 9 to be gripped, than the remaining part of the locking lever 7.
  • said material is constituted by an elastically deformable material, preferably natural or synthetic rubber.
  • the region 40 is preferably formed by an insert 41, made of said material, which is applied to the body of the locking lever 7 at a suitable recess 42 formed in the side of the locking lever 7 that cooperates with the elastic lamina element 6a in gripping the thread 9.
  • the insert 41 protrudes slightly from said side of the locking lever, and its surface that protrudes from the side of the locking lever 7 is conveniently blended with the surface of said side of the locking lever 7.
  • the insert 41 is limited only to the region of the locking lever 7 that makes contact with the elastic lamina element 6a when the thread 9 is gripped, so as to limit the extent of the sliding of the insert 41 against the elastic lamina element 6a and thus limit the wear of the insert 41.
  • the insert 41 also covers the region in which the shoulder 11a is formed.
  • the device according to the invention can be arranged proximate to the thread guides 3, as shown, or proximate to the thread aspirator port, if provided, which is usually provided in circular knitting machines for hosiery or the like.
  • the locking lever 7 has, on the opposite side with respect to its lower end, in which the shoulders 11a and 11b are provided, an extension 25 that protrudes upward from the supporting element 2 in order to allow, if required, the manual actuation of the locking lever 7.
  • the locking lever 7 can be in the active position, shown in Figure 1, or in the inactive position, shown in Figure 2.
  • the locking lever 7 is in the active position, before the end of the step for feeding the thread 9, i.e., before lifting the thread guide 3, the locking lever 7 is moved into the inactive position, shown in Figure 2.
  • the thread guide 3 is raised or otherwise moved into a position that prevents the needles 5 from engaging the thread, and the thread 9 remains engaged with the last needle fed.
  • the portion of thread 9 that lies between the thread guide 3 and the last needle that engaged it rises and moves toward the axis of the needle cylinder 4, arranging itself in the space of the locking lever 7 that is delimited by the shoulders 11a and 11b, which limit the possibility of lateral movements of the thread 9.
  • the shoulder 11b which is directed away from the axis of the needle cylinder 4 and is located between the axis of the needle cylinder 4 and the thread 9, limits, during this step, the possibility of movement of the thread 9 toward the axis of the needle cylinder 4.
  • the thread 9 is gripped between the region of the locking lever 7 at which the insert 41 is located and the elastic lamina element 6a.
  • the thread 9 is retained with absolute assurance even if the thread 9 is constituted by an elastic thread that has a small diameter and is fed in a pre-tensioned condition, and even if the elastic lamina element 6a is not perfectly parallel to the grip portion 8 of the locking lever 7.
  • the thread guide 3 When one wishes to resume knitting with the thread retained by the locking lever 7, the thread guide 3 is moved again into a position that is suitable to allow the thread 9 to be gripped by the needles 5, and the locking lever 7 is returned, by way of the actuation of the pneumatic cylinder 20, to the inactive position, in contrast with the action of the spring 24.
  • the device according to the invention fully achieves the intended aim, since by avoiding abnormal movements of the thread in the direction of the axis of the needle cylinder of the machine during the step in which feeding ends and the thread is engaged, it is capable of gripping the thread with absolute assurance during its cutting.
  • the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
